OT Details for NIRI

The instrument non-specific aspects of the Observing Tool (OT) are described elsewhere. Detailed information on NIRI Component of the OT and the NIRI Iterator is provided below.


The detailed component editor for NIRI is accessed in the usual manner, by selecting the NIRI component in the science program, and is shown below:

Data Format and Reduction

The Gemini IRAF MIDIR package has been released, consisting of scripts allowing basic reduction of imaging and spectroscopy data. Given the similarities in the reduction of data from T-ReCS and Michelle, this topic is covered in the mid-IR data reduction pages. The basic format of all Gemini data is explained in the Data section of the Gemini website.

OT Library

The Observing Tool libraries contain "pieces" of observations e.g. commonly used configurations, sequences, standard calibrations and ancillary information which may be copy-and-pasted into a new observation. The intent of these libraries is to speed the development of new science programs. As observing procedures and instrumental configurations may change from semester to semester (installation of new GCAL filters, for instance), it is advisable that PIs download the most recent libraries when defining new observations.

Observation Preparation

This section contains instructions for configuring T-ReCS at phase II. It is organised as follows:

Sensitivity Tables (AO: NGS and LGS)

Notes

  • The sensitivity tables assume photometric conditions (50%-ile cloud cover), grey time (80%-ile sky background) and an airmass of less than 1.2. Note however that the OH sky emission can vary by a factor of ~2 up or down during the night
  • Individual exposure times of 600s were assumed for all cases.
  • Observations are assumed to be at f/32 and dithered (target object in the field at all times); sky subtraction noise is included.
